Pythron

Con artistMartus Mazur defrauded an elderly Pythron couple in 2370 by obtaining their financial access codes and investing their money in his business, which promptly failed. The couple filed a complaint against him with Odo, who arrested Mazur. Under the influence of a machine changing the laws of probability, the Pythrons temporarily did not press the charges, but they later changed their mind again, so Mazur went back to prison.
